4d duke microscope integrated optical coherence tomography in a zeiss artevo 800

Conditions: Corneal Diseases; Retinal Diseases; Ocular Diseases

Summary: the study team will conduct the first in-human pilot studies using 4d mioct for imaging in the operating room. building on the earlier integration and wet-lab validations, the researchers will assess the system's ease of use, safety, and visualization of intended structures during various anterior and posterior segment ophthalmic procedures.

the purpose of this project is to capture research images from microscope integrated optical coherence tomography (mioct) integrated into a zeiss artevo 800 surgical microscope with an add-on investigational 3d oct scanner (hereafter called the 4d mioct) in participants undergoing clinically-indicated surgical procedures for a range of ocular diseases. the researchers will evaluate normal and abnormal microanatomy of the eye, image during surgical procedures, and track subretinal injections for therapeutic delivery during surgery (volumes measured/analyzed from the oct images after surgery). this study is an observational imaging study with no treatment interventions for research purposes. the population is 5 adult ophthalmic surgical patients scheduled for eye surgery at duke eye center, durham. up to 8 patients may be enrolled due to potential for surgery scheduling changes that would not allow research imaging on a surgery day for up to 3 patients. research activities consist of investigational 4d mioct integrated into zeiss artevo 800 imaging of the eyes during surgery and collection of clinical data and other imaging from the participant's medical record, clinical visit and surgical procedure. additional imaging of the participant's eye performed for clinical care will be extracted from the medical record for comparison to the intraoperative images. in this initial pilot, comparisons will enable design of future studies for accuracy, precision and reproducibility of the research device in eye surgery. for study participants there is no additional risk to the participant beyond what is normal for their ophthalmic surgery. no medications or surgical interventions/activities will be performed for research purposes. images will be captured during the standard care ophthalmic microsurgery. this research will utilize the data gathered during oct imaging performed as described above. the data collected from the oct systems will be analyzed offline to allow for image processing and alternate visualizations of the area under study. the data gathered from 4d mioct imaging will be compared to existing clinical studies (performed as part of standard of care) on the participant, should they exist, for the purpose of identifying whether new information is gained by 4d mioct. researchers will review the participant's medical record for up to three eye care visits prior to surgery and record information related to ocular health, eye examinations and imaging and prior ophthalmic treatment. no additional clinical studies will be performed for the purpose of this study.

Eligibility criteria:
inclusion criteria: * adult participants 18 years of age and older * patients undergoing surgery for ocular disease * adults able and willing to give informed consent to participate in the study exclusion criteria: * patients with any ocular disease that restricts the ability to perform oct scanning
